viktelen [127]

Answer:

AC=BD

AB\perp BC

Step-by-step explanation:

A parallelogram is a quadrilateral (4-sided polygon)  that has two pairs of parallel sides.  

In this sense, this figure shows a especial parallelogram called <u>rectangle</u>, since its four sides form right angles (90\°).

Hence:

AD\parallel BC

AB=DC

AD=BC

The probability of spinning an odd number, flipping heads and then spinning a 3 is?
Olenka [21]
<h3>Answer:  5/162</h3>

===================================================

Work Shown:

A = probability of landing on an odd number

A = 5/9 because there are 5 odd numbers out of 9 total

B = probability of getting heads

B = 1/2

C = landing on 3 on the spinner

C = 1/9

Multiply the values of A,B,C

A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%

Lina20 [59]
So 1, 4, 9, & 16 are all perfect squares 
Probability = 4/20 = 1/4 = 20% 
                        ^ Either of these could work depending on the problem.
